Z64 source question

[angrylion]

Can someone explain me what does this string from z64 RSP plugin mean?
It's in main_rsp.cpp, in DoRspCycles function:

DWORD TaskType = *(DWORD*)(z64_rspinfo.DMEM + 0xFC0);

Is there something important at FC0h in RSP's DMEM? I couldn't find a clue.

Looks like it is "Task Type" (video, audio)

Thanks, you are very helpful!
So these values are ucode-dependant and Ziggy checks them to allow HLE audio with his plugin. Yes, this makes sense now.
